Finland's parliament has voted to make 34-year-old Social Democrat Sanna Marin the world's youngest serving prime minister and she will lead a five-party coalition cabinet, consisting of 12 female and seven male ministers. Marin will struggle to defend her leftist views against the Center Party, which says it wants action to boost Finnish employment to pay for the costly welfare state. Finland's government resigned last week after the Center Party said it had lost confidence in Social Democrat Prime Minister Antti Rinne over his handling of a postal strike.
